I'm very glad you are posting, thinking, and asking questions. Thank you.
I believe, and always have, that if I can imagine it - it is possible.
I not only can imagine what Einstien was throwing out there - I embrace it as dead on. Hence, I've got a fairly broad ability to imagine, for better or worse.
I guess I'm trying to exert self-control more than anything. That involves some degree probing, which tends to come at things from both (polarities) sides.
